I have 04 ram slt with the 5.7L engine. Suddenly one day while driving the truck wouldnt go into 4th or 5th gear. I checked the error codes and it came up with the tcm, 4th and 5th gear codes. I changed both the filters. And still it doesnt go into gear. In fact now i believr it only goes into 1st and 2nd gear. I guess im asking if it is caused by the ecm or is it something else
